Convince the brand team to pick a couple fallback system fonts and swap the brand font in after it has loaded. You will have a bit of content reshuffling no matter what you do but it's better than the alternative. There are directives to do this in pure CSS but I seem to remember they had some unfortunate implementation bugs so when I did this it was easier to do it in JS.
